【摘要】 用苯乙烯和二乙烯基本等配制的混合液浸渍多孔聚丙烯膜，在特制的模具中聚合，经过一系列处理得到无色透明的PP－Poly（St-Co－DVB）复合膜。此膜具有明显优越于聚丙烯和聚苯乙烯的力学性能，是合成高强度的高子交换树脂膜的重要基膜。我们用红外、扫描电镜、X-射线、电子能谱等多种方法研究其结构，指出优异的力学性能来源于内部的互穿网络结构及其在力的作用下的协同作用。更多还原

【Abstract】 Firstly PP membrane was dipped in the mixture of styrene and DVB, polymerhation was completed in a special instzument, and then a transparent membrane of PP-Poly (St-Co-DVB ) were obtained after purification treatment. The membrane excels PP or PSt membrane in mechanics and can be used in preparation of ion exchange membrane. IR,SEM, X-ray and XPS were used to study its structure. According to the results, a explanation was given to the relation between structure and properties.更多还原
